Avren Rocks
Avren Rocks are three adjacent rocks situated in the interior of Micalvi Cove in the south extremity of Robert Island, South Shetland Islands. The group extends in north–south direction and is wide. The rocks were first mapped in 2008 by a Bulgarian team. They are named after two settlements in Varna and Kardzhali provinces situated in northeastern and southeastern Bulgaria respectively.
